SPECIFICATION forming part of Letters Patent No. 34:3,990, dated June 22, 11886.

Application filed March 31, 1886. Serial No. 197,304. (No model.)

Figure 1 is a plan of an insole of my im proved construction. Fig. 2 is a vertical section on the line 00 x of Fig. 1, three layers being shown. Fig. 3 is a vertical section through an insole composed of two layers.

My invention consists in an inner sole formed of layers or thicknesses, havingfor its leading feature an upper layer composed of teaseled woven hair, either spun or not, said layers or thicknesses being united by adhesive material, sewing, or other suitable fastening, the hair of the upper layer affording a soft yielding bearing forthe sole of the foot and contributing to the warmth of the same.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which 1 have carried it out.

One description of insole embodying my invention is formed in the following manner. A Woven fabric composed of warps of cotton, linen, or Woolen, and a filling of the hair of animals.for instance, oX-hair either spun or not, and having its upper surface teaseled, so as to cause the ends of the hairs to separate or stand off from the Warp, is cut into sheets a of convenient sz and attached by glue or other adhesive material, I), to a second sheet, a, of similar size, of card-board, straw-board, pasteboard, leather-board, wood veneer, cork,

cloth, &c., the said adhesive substance being laid upon the upper side of this second sheet or upon the under side or unteaseled surface of the wovenhair fabric "to which it is to be attached. A third sheet, d, of similar size, of paper or leather, either enameled or not, with its smooth surface outside or underneath, is

then attached by glue or other adhesive substance, e, and the three layers a c (2 left to dry, after which a pattern of the desired size and form of insole is placed on the three-ply sheet and the latter cut up into insoles, and a line of stitching, h, run around close to the edge of each insole, to keep the edges of the layers from separating.

The three layers a c 01 may be united by rows of stitching either made longitudinally or transversely with the sole,,and the adhesive material may be dispensed with, or the latter may be employed in connection with the stitching.

The insole may consist of only two thicknesses or layers, Fig. 3, the upper one being of Woven hair,with its upper or outer surface teaseled, and the lower layer of enameled leather, paper, or cloth.

I claim An insole consisting of an upper layer or ply of a teaseled woven-hair fabric and one or more layers of card or other board, cork, leather, cloth, 850., united by adhesive mateterial or stitching, or by both, as described.

Witness my hand this 25th day of March, 1886.
